looks like one of those 'unstable' training ideas... always just looks dangerous to me

Kinda like balancing on a giant bouncy ball while squatting right? lol Where's that pic? People get so fucking hung up over the silliest shit. I mean look at Arnold and Oliva. Look what they had to work with in the 60's and 70s. This is a shitty gimmick. I hope to never see it in person.
